About this trial

The study is intended to assess the safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of AZD4512 in patients with relapsed/refractory B-Cell acute lymphoblastic leukemia (r/r B-ALL).

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

16 years old in Module 1 (US only: ≥18year)

12 years old in Module 2

Participants must have relapsed or refractory B-ALL ('relapsed' defined as bone marrow blasts > 5% or reappearance of blasts in PB)

Module 1 (DE): Ph(-) B-ALL and Ph(+) B-ALL - R/R

Disqualifiers

Burkitt lymphoma and leukemia

Isolated extramedullary disease; Active testicular or CNS (> CNS1) involvement

Unresolved non-heme toxicities Grade ≥ 2 (except alopecia, stable Grade ≤ 2 neuropathy, vitiligo, endocrine disorders controlled with therapy)

History of drug-induced non-infectious ILD/pneumonitis requiring oral or IV steroids or supplemental oxygen or where suspected ILD/pneumonitis cannot be ruled out by imaging at screening

Trial design

Design model

Sequential

Treatments tested in this trial

  • AZD4512 monotherapy

    Combination product

    Patients will receive AZD4512 as monotherapy via intravenous infusion. AZD4512 is an antibody-drug conjugate targeting CD22

Trial outcomes

Primary outcomes

1

Module 1 (Dose Escalation): Number of participants with dose-limiting toxicities (DLTs).

DLTs are dose-limiting toxicities as defined in the study protocol.

Time frame
From first dose up to 21 days (DLT period).
2

Module 1 (Dose Escalation): Frequency, duration and severity of treatment-emergent adverse events (TEAEs), treatment-related adverse events (TRAEs), and serious adverse events (SAEs)

Assessed by the CTCAE criteria version 5.0

Time frame
From date of first dose of AZD4512 up until 30 days post last dose of AZD4512 (on average 6 months)
3

Module 1 (Dose Escalation): Frequency of dose interruptions, modifications, delays, and discontinuations due to AEs

Time frame
From date of first dose of AZD4512 up until 30 days post last dose of AZD4512 (on average 6 months)
4

Module 1 (Dose Escalation): Number of participants with clinically significant changes in laboratory values, ECGs, performance status, and vital signs

Time frame
From date of first dose of AZD4512 up until 30 days post last dose of AZD4512 (on average 6 months)

Secondary outcomes

1

Module 1 (Dose Escalation): Plasma PK parameters of AZD4512

To characterize the PK of AZD4512 as monotherapy in participants with R/R B-ALL.

Time frame
From date of first dose of AZD4512 up until 30 days post last dose of AZD4512 (on average 6 months)
2

Module 1 (Dose Escalation): Total antibody and total unconjugated payload

To characterize the PK of AZD4512 as monotherapy in participants with R/R B-ALL.

Time frame
From date of first dose of AZD4512 up until 30 days post last dose of AZD4512 (on average 6 months)
3

Module 1 (Dose Escalation): Area Under Curve (AUC)

To characterize the PK of AZD4512 as monotherapy in participants with R/R B-ALL.

Time frame
From date of first dose of AZD4512 up until 30 days post last dose of AZD4512 (on average 6 months)
4

Module 1 (Dose Escalation): Peak Plasma Concentration (Cmax)

To characterize the PK of AZD4512 as monotherapy in participants with R/R B-ALL.

Time frame
From date of first dose of AZD4512 up until 30 days post last dose of AZD4512 (on average 6 months)
